Dyno Results

[macncheese]

With 1500 miles on the odometer, my Cooper S pulled 162 at the wheels. Hows THAT for drivetrain loss? I'm not really believer in dyno pulls for numerical values. Its more for behavior trends in my opinion but I know theres some on this board who feel differently. I'll post the graphs as soon as I have them.

(nice looking car, too!)

Other interesting tidbits:

- dyno set off the abs, flat tire monitor, and DSC lights
- they cleared themselves after driving about 50ft

- the speedo sensor must be off the rear tires because the speedo never moved and the trip computer registered 0.

- removing the exhaust from the catback created a huge difference in .......

I'll save that for next time

Atglen, PA

Fairly close to Lancaster and not much else. We actually passed a store called "Amish Stuff and etc"

im gonna spoil it..he had 1 hp gain i think he said...from the exhaust being removed from the cat back....must be because of xbackpressurex. haha

What's the most accurate conversion to get flywheel figures?

ALso, the S and Cooper will loose different ammounts I assume, as they have different gear boxes etc.

Sound. The exhaust sounded great but was unbearably loud with the catback removed. The curves were nearly identical with the catback piping unbolted (compared to stock). Everyone held their ears during the dyno runs as it sounded like the minions of hell were being released from the tailpipe. I'm not sure this means anything yet but its an interesting observation. We'll see where it goes with a new exhaust.

Deconstructing my car in the name of performance... exactly what i said i wouldnt do.

[Drakken]

BTW, both cars were running rich. Macncheese's S ran very rich with the exhaust off. My guess is that the ECU was confused with the front tires spinning and the rear not. The speedometer gets it's info from the rear.

[districtofc]

you think that the ecu knew that the exhaust was off? or the ecu knew that the back wheels werent spinning? either way that would be kinda weird for the ecu to compensate by spitting more fuel...wouldnt you say? i cant imagine a car running a fuel map by a wheel sensor...i could believe an 02 sensor but isnt it before the cat?
